Overview
The Broadcom Limited 4N25-360E is a single-channel transistor output optocoupler housed in a PDIP-6 Gull Wing package. It features an NPN phototransistor output with a maximum collector current of 100 mA and a collector-emitter voltage rating of 30 V. The device provides 2500 Vrms insulation voltage and supports a forward current of up to 80 mA. Key electrical parameters include a minimum current transfer ratio of 20%, a forward voltage of 1.5 V, and a maximum collector-emitter saturation voltage of 500 mV. Switching characteristics specify rise and fall times of 3 µs each.
Feature Summary
- Provides galvanic isolation via an infrared LED coupled to an NPN phototransistor
- Supports surface mount installation in a standard six-pin gull wing package
- Delivers high insulation voltage for reliable signal transmission across isolated boundaries
Applications
- General purpose signal isolation in industrial control systems
- Interface circuits for microprocessor-based logic systems
- Switching power supply feedback loops
Procurement Notes
Verify the specific ordering suffix matches the required RoHS compliance status and packaging configuration. Confirm that the lead time aligns with project schedules as availability may vary by region. Ensure the procurement channel is authorized to guarantee component authenticity and traceability. Cross-reference the manufacturer part number with official datasheets to validate technical specifications before finalizing orders.
Selection Notes
Select this component when moderate speed switching is sufficient for the application, given its 3 µs rise and fall times. Consider the 100 mA collector current limit for load driving requirements. Evaluate the 2500 Vrms isolation rating against system safety standards. Compare against higher-speed alternatives if data rates exceed the capabilities of standard transistor output devices.
Part Context
This device belongs to the standard family of transistor output optocouplers manufactured by Broadcom Limited. It serves as a foundational component for basic isolation tasks in electronic circuits. The product line is widely recognized for compatibility with general-purpose digital logic interfaces and power control applications requiring electrical separation between input and output stages.
Replacement Considerations
Direct substitutes include other single-channel NPN phototransistor optocouplers with identical pinouts and similar electrical ratings. Verify that replacement parts meet the same 2500 Vrms isolation and 100 mA current requirements. Check for equivalent switching speeds and current transfer ratios to ensure circuit performance remains unchanged.
